Testing Computer Software p. 275 Syllabus Section 2.2

“Testing Activities After First Functionality: …The programmer does unit testing. Someone (programmer, tester, programmer’s assistant, someone) should start testing the program from the outside.”


6. During the component or subsystem testing, testers focus on bugs in constituent pieces of the system.

a. True

b. False

a. True


“During the component or subsystem testing, testers focus on bugs in constituent pieces of the system.”


7. Select a reason that does not support the idea of incremental testing:

a. It is easier to pin down the cause of an error.

b. The programmer can see internal boundaries in the code that are completely invisible to the outside tester.

c. Testing of only one module, any errors are either in that module or in a simple program wrote to test it.

d. The programmer focuses on each module individually, which yields to better test coverage.

b. The programmer can see internal boundaries in the code that are completely invisible to the outside tester.

Testing Computer Software p.42 and 45 Syllabus Section 2.2.2

“Internal boundaries: The programmer can see internal boundaries in the code that are completely invisible to the outside tester.” p. 42

Valid reasons to support incremental testing can be found on p. 45 in the second paragraph.


8. Integration testing:

a. involves testers look for various types of bugs in the entire system, fully integrated.

b. involves testers looking for bugs in the relationships and interfaces between pairs and components of groups of components in the system under test.

c. occurs often in a staged fashion.

d. B & C

e. A & B

d. B & C


“Integration or product testing involves testers looking for bugs in the relationships and interfaces between pairs and components of groups of components in the system under test, often in a staged fashion.”


9. System testing tends toward the _____ area of the testing spectrum.

a. behavioral

b. functional

c. performance

d. reliable

a. behavioral


“System testing tends toward the behavioral area of the testing spectrum.”


10. A test run during System Testing is:

a. Error recovery.

b. Terminal handling.

c. Installation.

d. Keyboard handling.

a. Error recovery

Testing Computer Software p.54-57 Syllabus Section 2.2.3

“SOME TESTS RUN DURING FUNCTION AND SYSTEM TESTING“


11. Acceptance testing is:

a. validating end-to-end functionality based upon requirements.

b. checking whether the software is stable enough to be tested.

c. testing usability of the systems interfaces.

d. None of the above.

b. checking whether the software is stable enough to be tested.


“Acceptance testing

Each time you receive a new version of the program, check whether it’s stable enough to be tested.”


12. Acceptance testing is the demonstration that a system meets requirements.

a. True

b. False

a. True


“Acceptance testing, in contrast, often tries to demonstrate that a system meets requirements.”

Anyone concerned about the contradiction between this answer and the one provided in question #11? The books have distinctly different interpretations of the term Acceptance Test.


13. Which is not indicative of Black Box testing?

a. Performed by the testing group

b. Identifies how previous fixes have caused side effects.

c. Identifies how previous fixes failed.

d. Fails to identify masked bugs because it skips regression testing.

d. Fails to identify masked bugs because it skips regression testing.

Testing Computer Software p.50 Syllabus Section 2.3, 2.3.1

“BLACK BOX TESTING ”


14. Functional tests are:

a. sometimes has the same meaning as behavioral tests.

b. simultaneously designing, developing, and executing tests.

c. must be augmented with other test approaches to deal with potentially important quality risks such as performance, load, capacity, and volume.

d. A & C.

d. A & C.


“Functional tests: Sometimes this phrase has the same meaning as behavioral tests… must be augmented with other test approaches to deal with potentially important quality risks such as performance, load, capacity, and volume…”


15. The difference between volume tests and stress tests is:

a. Testing the audio components of an application vs. testing the breaking point of the system under load.

b. The study of the program’s ability to deal with the largest task vs. the study of the program’s response to peak bursts of activity.

c. The ability of a system to sustain load vs. the ability of a system to handle imported fields a large size.

d. None of the Above

b. The study of the program’s ability to deal with the largest task vs. the study of the program’s response to peak bursts of activity.


“Volume tests study the largest task a program can deal with.”

“Stress tests study the program’s response to peak bursts of activity.”


16. Structural testing is not:

a. glass box testing.

b. proper selection of program or subprogram paths.

c. feeding the component input and examining the output.

d. exercised during the battery of tests.

c. feeding the component input and examining the output.


“Structural testing is glass box testing. The main concern is proper selection of program or subprogram paths to exercise during the battery of tests.”


17. As a result of a change in the system under test, a new revision of the system, Sn+1, contains a defect not present in revision Sn,

the quality of the system is has progressed:

a. True

b. False

d. False


“As a result of a change in the system under test, a new revision of the system, Sn+1, contains a defect not present in revision Sn, the quality of the system is has regressed.”


18. In order to reduce the time needed for regression testing you can apply the following method(s):

a. Automate if you can.

b. Combine test cases.

c. Designate some tests for periodic testing.

d. Narrow focus of your testing scope.

a. Automate if you can.

b. Combine test cases.

c. Designate some tests for periodic testing.

19. Maintenance testing of the retirement of a system may include:

a. Operations tests of the changed software.

b. The testing of data migration.

c. Archiving if long data-retention periods are required.

d. B or C.

d. B or C.

CTFL Syllabus p.26 Syllabus Section 2.4

“Maintenance testing for the retirement of a system may include the testing of data migration or archiving if long data-retention periods are required.”


20. Acceptance testing may occur at more than just a single test level. With the exception of:

a. A COTS software product may be acceptance tested when it is installed or integrated.

b. Acceptance testing of the usability of a component may be done during component testing.

c. Acceptance testing after a change has been released to the user community.

d. Acceptance testing of a new functional enhancement may come before system testing.

c. Acceptance testing after a change has been released to the user community.

CTFL Syllabus p.22 Syllabus Section 2.2.4

“Acceptance testing may occur as more than just a single test level, for example:
